JCB046L

Overview

The JCB046L is a GPS and LTE combination antenna manufactured by JC Antenna. It features a puck-style design with dimensions of D81.3mm diameter and 14.6mm height. The unit operates at an impedance of 50Ω. For GPS, it covers the frequency range of 1575.42±3MHz with right-hand circular polarization (RHCP), providing a zenith gain of 2dBic and a VSWR of less than 1.5. The integrated Low Noise Amplifier (LNA) offers a gain of 28±2dB with a noise figure under 2dB and an axial ratio of 3dB maximum. It supports EV charging station applications.

Feature Summary

• Combines GPS and LTE reception capabilities in a single compact puck form factor
• Integrated Low Noise Amplifier enhances signal sensitivity for weak satellite signals
• Right-hand circular polarization ensures reliable GPS tracking performance
• IP67 ingress protection rating enables operation in harsh outdoor environments

Applications

• Electric vehicle (EV) charging stations
• Fleet management systems requiring combined location and cellular connectivity
• Telematics units for commercial vehicles
• IoT gateways needing simultaneous GNSS and LTE data transmission

Procurement Notes

Verify the specific connector type and cable length configuration required for your integration, as these may vary. Confirm that the LNA power requirements align with your system's voltage supply. Ensure the mounting surface is suitable for the magnetic or adhesive base to maintain the specified IP67 seal integrity during installation.

Selection Notes

Select this model when both high-precision GNSS positioning and cellular data transmission are required from a single physical location. The integrated LNA makes it suitable for installations where signal loss through cables or enclosures is a concern. Verify compatibility with the specific LTE bands used in your target region, as the datasheet specifies general LTE coverage without listing exact band numbers.

Part Context

JC Antenna produces a range of RF antennas for automotive and industrial use. The JCB046L belongs to their combo antenna series, designed to reduce installation complexity by merging multiple radio functions into one housing. This approach minimizes cable routing and potential points of failure compared to using separate discrete antennas for GPS and LTE modules.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model. When replacing, ensure the new antenna matches the 50Ω impedance and physical mounting footprint. Verify that any alternative provides comparable LNA gain and noise figure specifications to maintain system performance levels.
